ABSTRACT

A multi-part electronic device has a mode with at least two overlapped device parts comprising a first camera part mounted on a first device part and a second camera part mounted on a second device part. At least one of the first and second camera parts is resiliently mounted such that contact between the first and second camera parts when the first device part and the second device part are overlapped with each other aligns the first camera part and the second camera part within a selected angular deviation between the camera parts&#39; respective optical axes. A camera part having a body and a flexible mount and a method of reducing tilt error are also described.

BACKGROUND

Many kinds of today's electronic devices include a digital camera. Suchcameras add to the features and functionality of electronic devices.

One type of electronic device is a multi-part electronic device in whichthere are multiple parts used in association with each other that aretypically coupled together physically. For example, there are two-partelectronic devices where first and second parts are coupled together bya hinge, a sliding arrangement or another configuration. Such electronicdevices can include mobile devices (including mobile phones), tablets,laptop computers, other types of computing devices, game controllers,etc.

In some multi-part electronic devices, at least two of the multipleparts can be positioned to overlap each other to provide a specificoperation for the camera. As just one example, the overlapped mode mayprovide for additional focusing options based on using optical elementsin a second part of the device with a main camera part in a first partof the device when the first and second parts of the device areoverlapped.

In practice, it is difficult to achieve suitable alignment betweenmultiple camera parts of a multi-part electronic device that can bemoved relative to each other.

In one implementation, the resilient mount is sized to fit around therespective camera part and to seal a space between the respective camerapart and an opening formed in the respective device part for the camerapart. The resilient mount can be configured for adhesive mounting to aninner surface of the respective device part.

DETAILED DESCRIPTION

FIGS. 1A and 1B are side elevation views of a representative multi-partelectronic device 100 having multiple camera parts. In therepresentative implementation of FIGS. 1A and 1B, the multiple parts ofthe multi-part electronic device 100 include a first device part 102 anda second device part 104 that are coupled to each other, e.g., by ahinge 106. The first device part 102 has a first camera part 110. Thesecond device part 104 has a second camera part 112.

The first camera part 110 and the second camera part 112 have at leastone mode of operation in which they are coupled together, such as in theclosed position of the device 100 as shown in FIG. 1B. Optionally, oneor both of the first camera part 110 and the second camera part 112 canhave a mode of operation in which it is used individually. Although twodevice parts are illustrated in FIGS. 1A and 1B for convenience, themulti-part device 100 can include more than two parts. Similarly, themulti-part device can include more than two camera parts. It is notedthat the terms “first” and “second” are used for clarity only, and donot imply any logical precedence between the parts. Rather, the partsare interchangeable, so, e.g., the first device part can have the secondcamera part and the second device part can have the first camera part.

As used herein, a “camera part” refers to a device, module, unit,element, or part thereof, in which there is at least one image sensorcapable of capturing digital image frames comprising image data whichcan be used to reproduce and display digital images. Such a camera maybe implemented, for example, as a plain digital image sensor which isconnected to an appropriate external power supply and control unit(s)and equipped with an appropriate housing and optical system. In otherimplementations, a camera may be configured as an imaging module orcamera module which itself may comprise in addition to the digitalsensor element, any appropriate mechanical and optical elements, as wellas control electronics. As used herein, the “first camera part” and“second camera part” together include all or some subset of the variouscamera components. Each of the first camera part and the second camerapart includes at least one component effecting the operation when thefirst camera part and the second camera part are coupled together foruse in an operation mode as is described below in greater detail.

FIG. 2 is a side elevation view of a portion of a multi-part electronicdevice having multiple camera parts that are shown slightly separatedfrom each other and before alignment has taken place. As can be seen inFIG. 2, an optical axis as OA1 for a first camera part 210 in a firstdevice part 202 is slightly out of alignment with a second optical axisOA2 of a second camera part 212 in a second device part 204. In thefirst device part 202, the first camera part 210 is configured to extendthrough a first camera part opening 214 and protrude slightly by aprotrusion distance P1 relative to an adjacent surface 206A. In theillustrated implementation, the first camera part 210 has a protectionwindow 228 or other outermost component that protrudes relative to thesurrounding structure.

In the implementation of FIG. 2, the second camera part 204 isconfigured similarly. That is, the second camera part 204 is configuredto extend through a second camera opening 216 and protrude slightly by aprotrusion distance P2 relative to an adjacent device part surface 206B.In some implementations, the protrusion distance P1, P2 for each of thecamera parts 210, 212 is about 0.15-0.20 mm.

The first camera part 210 is resiliently coupled to first device part202 by a first camera mount 218. At least a portion of the first camerapart mount 218 is adjustable to allow the first camera part 210 to moverelative to the first device part 202, as is described in detail below.In the illustrated implementation, the first camera part mount isadjustable by way of being at least partially resilient. Similarly, thesecond camera part 212 can be adjustably mounted relative to the seconddevice part 204 by a second camera mount part 240. The second cameramount part 240 can have at least a resilient portion allowing the secondcamera part 212 to move relative to the second device part 204, as isalso described below. It should be noted that in some embodiments, onlyone of the camera parts 210, 212 is resiliently mounted, and the otheris fixed.

As shown in FIG. 3, when the multi-part electronic device is moved to aclosed position, the first camera part 210 and the second camera part212 contact each other. Because the contact is configured to occurprecisely between geometric features having a known relationship to eachother, each camera part self-aligns, and, as a result, the pair ofcamera parts are mutually aligned. More specifically, the contactbetween the first and second camera parts 210, 212 can be configured tooccur along precision surfaces such as respective surfaces of theprotection window 228 and the protection window 250, with this contactbetween the camera parts 210, 212 tending to move each slightly onaccount of the resiliency of its camera part mount 218, 240,respectively.

The flatness grade and stability of the glass, plastic or other materialused for the protection window or other outermost component can beselected to ensure that the surface provides sufficient alignmentaccuracy. Conventional glass and plastic materials used for suchapplications are sufficient in this regard. As an example, for a 10 mmdiameter window, one side of the window needs to be within approximately29 μm of the opposite side of the same window to ensure that thedeviation in the tilt axis for that window is about 10 minutes (alsowritten as 10′) or less. The protection window may be used as a datumsurface during assembly of the camera part, so there are advantages torelying on its known attributes in operation of the electronic device aswell.

The camera mounts 218, 240 can be made of rubber, soft foam, silicon,latex or another suitable material having sufficient flexibility andresiliency for the specific application. The camera mounts 218, 240 alsoserve to seal the respective openings from intrusion of dust, moistureand other undesired substances.

For sake of illustration, the optical axis OA1 and the optical axis OA2would appear to be in perfect alignment in FIG. 3. In practice, however,alignment within a selected angular deviation range is sufficient. Forexample, in some implementations, it is sufficient for the optical axesOA1, OA2 to be aligned with 10′ (i.e., such that their respect tiltangles together combine for a tilt error of 0 to 10′). In someimplementations, the physical self-alignment approach described hereinis used in conjunction with digital techniques that adjust one or moreparameters of camera output to compensate for position errors.

FIG. 4 is a side elevational view of the first camera part 210, which isshown in isolation for clarity. The camera mount 218 has an innerperiphery 220 and an outer periphery 222. The camera mount 218 can besecured in place on an interior surface 226 (FIG. 3) of the device partwith suitable adhesive 224. In some implementations, an adhesive tapecan be used. The protection window 228 is secured to a housing 260 (orbody). The housing 260 can house optical elements, including one or morelenses, filters, etc., which are shown schematically at 262, and animage sensor 264. The image sensor 264 can be supported by a printedcircuit board or printed wire board 266 having a connector 230.

FIG. 5 is a side elevational view of another implementation having twoadditional optional features. In some scenarios, it is desirable toshift one or both of the camera parts, such that one is moved laterallyrelative to the other, as well as to adjust the tilt of the opticalaxes. For example, it is possible that bringing the protection windowsinto contact with each other causes the optical axes to approachparallelism with each other, but that they are laterally offset fromeach other and thus not coaxial. So, one or both camera mounts can beconfigured to provide for lateral movement in the direction of thedouble arrow shown in FIG. 5 and in perpendicular directions in the sameplane.

In the example of FIG. 5, a first camera part 310 has a camera mount 318that is similar the camera mount 218 described above, but includes afold, baffle or other structure 325 along at least portions of itsperiphery that can deform to permit the protection window 228 andattached housing to move laterally while the seal is maintained.

Second, the first camera part can include one or more pairs of magnetsto assist in achieving the lateral movement necessary for alignment. Forexample, there can be a first pair of magnets, such as a magnet 360mounted to the movable housing and a magnet 362 of a second camera part(the second camera part and second device part have been omitted fromFIG. 5 for clarity). In the illustrated example, the second magnet 362has a fixed position, and when the second device part is overlapped withthe first device part 310 as shown, the attraction force between themagnets 360 and 362 tends to move the protection window 228 and attachedhousing to the left in the figure. If provided, the fold 325 shown onthe left side of the figure is compressed, and the fold on the rightside of the figure tends to be stretched to accommodate the movement inthe leftward direction. Optionally, one or more pairs of magnets may beprovided, such as the magnets 364 and 366.

FIGS. 6A and 6B shown an electronic device 400 having a differentgeometry in which the first and second device parts 402, 404 arestep-shaped and nest together. In the electronic device 400, the firstcamera part 410 and the second camera part 412 are positioned oppositethe hinge 406.

Another representative geometry of a multi-part electronic device isshown in FIGS. 7A and 7B. A device 500 has first and second device parts502, 504 that slide or translate relative to each other to positionfirst and second camera parts 510, 512 in an overlapped configuration(FIG. 7B). Other configurations are also possible. In addition, the sameapproach can be applied to providing self-alignment in a separateaccessory lens that is fit over a camera part in an electronic device(e.g., to extend the range of the camera range).

Referring to FIG. 8, an implementation of a method of reducing tilterror between multiple camera parts in a multi-part electronic devicecan be described. In step 810, a first camera part is adjustably mountedto a first device part. In step 820, a second camera part is mounted toa second device part. One or both of the camera parts may be adjustablymounted. If one of the camera parts is mounted with sufficient precisionto achieve a desired alignment, then only the other camera part may needto be adjustably mounted. In step 830, the first and second device partsare overlapped such that the first and second camera parts contact eachother. In step 840, and assuming only the first camera part isadjustably mounted, the contact between the camera parts urges the firstcamera part to move to adjust its tilt axis and/or lateral position toachieve alignment with the second camera part within a selected range ofaccuracy.

According to the described approach, because precision surfaces (e.g.,the protection windows or other suitable geometric features) are broughtinto contact with each other, each precision surface's optical axis(which is defined to be normal to that surface) is closely aligned withthe other. To the extent that the camera parts move in oppositedirections relative to the other in achieving alignment with each other,errors in alignment between each camera part and its respective devicepart are reduced. As a result, the overall alignment of the opticalsystem is improved.

FIG. 9 is a system diagram depicting a representative electronic ormobile device 900 according to any of the above implementations,including a variety of optional hardware and software components, showngenerally at 902. Any components 902 in the mobile device cancommunicate with any other component, although not all connections areshown, for ease of illustration. The mobile device can be any of avariety of computing devices (e.g., mobile phone, smartphone, tablet,handheld computer, Personal Digital Assistant (PDA), laptop computer,game controller, etc.) and can allow wireless two-way communicationswith one or more mobile communications networks 904, such as a cellular,satellite, or other network.
